A robust approach should be considered when estimating regression coefficients in multi-response problems. Many models are derived from the least squares method. Because the presence of outlier data is unavoidable in most real cases and because the least squares method is sensitive to these types of points, robust regression approaches appear to be a more reliable and suitable method for addres...

Ingenol is a diterpenoid with unique architecture and has derivatives possessing important anticancer activity, including the recently Food and Drug Administration-approved Picato, a first-in-class drug for the treatment of the precancerous skin condition actinic keratosis. Currently, that compound is sourced inefficiently from Euphorbia peplus. Here, we detail an efficient, highly stereocontro...

We consider distribution of random variable $\xi=\tau+\eta$, where $\tau$ and $\eta$ independent variables, moreover has classic Cantor type is a with identically distributed digits the nine-digit representation. With additional conditions for distributions $\eta$, sufficient singularity $\xi$ are specified. To substantiate statements, topological-metric analysis representation numbers $x\in [0...

We report multiband observations of the Optical Transient (OT) associated with GRB000301c carried out between 2–4 March 2000 using the 2.34-m Vainu Bappu Telescope (VBT) at Kavalur, India. When combined with other reported data, the initial decline in the R-band magnitude with log (t − t0), the time since the burst is fit with a slope α1 = -0.70 ± 0.07 which steepens after about 6.0 days to a s...
